comphead opened a new issue, #3817: URL: https://github.com/apache/datafusion-comet/issues/3817
### What is the problem the feature request solves? Observed the issue when Comet is not fully utilizing Spark cluster parallelism. Input: 1200 HDFS files, number of Spark planned tasks: 1800. Every file is splittable, so Spark utilizes all 1800 scanning and writing the shuffle whereas Comet utilizing only 1200 tasks having 600 idle. I was not able to reproduce the same locally, will try on local HDFS later ### Describe the potential solution _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
